1. NO BLATANT PIRACY. This includes reproducing homebrew less than 10 years old, with the exception of free software.2. No advertising your reproductions, with the exception of free software.3. Be nice. See RFC 1855 if you aren't sure what this means.

The game works for about 30 minutes and then it would start glitching and finally it would just crash and become unplayable. Even before the crash, the game seems a bit jumpy and there are some weird lines at the bottom of the screen. Still playable though until it completely starts glitching and crashing.

I've checked and rechecked my wiring and continuity on all solder points and I can't seem to find any issues.

The ROM plays perfectly fine while emulated. I even tried to burn two different versions of the patched ROM and still had issues.

I followed the same wiring except for pin 24 on PRG which I soldered to pin 16. Pin 16 is GND also, correct?

See below pics of the board.

I have just realized that every dump of this ROM has a glitch. Please see the video below. You can see the scrambling on top of the screen every now and then. Could this be worsened after programming the game and playing on actual hardware?

As a TOP3000 owner I can say this: The ZIF socket is a FAKE. It's not a real 3M part. and it is notoriously horrible. I replaced it on mine with a real 3M socket (there's just a low profile socket underneath) and it works much better.

I've created a few other repros using TOP3000 without any issues. I am also using to burn PICs for some other project and it works fine. I hope the ZIF socket won't fail on me if what you're saying is true.

Anyways, the glitch in the game seems to be apparent on original Famicom carts as well! I guess there's nothing that can be done about that :/

With the repro the glitching is a bit amplified however the game is still very playable.

As for the random crashing, I've realized that a good clean of the pcb board after soldering solved the issue. I use flux to help melt the old solder joints and it splatters all over the board while I'm desoldering the ROMs. I guess that causes some kind of shorting if left uncleaned.
